Now Amazon is offering a $2 credit for anyone who connects their twitter with Amazon MP3. You are connecting your account, posting a tweet, and following @amazonmp3 and @imdb, and a $2 credit will be applied to your account. It's REALLY easy, all you have to do is hit a button!
What can you get for $2 right now? They posted a whole new list of 25 cent songs, so you could get 8 of these popular downloads. You could also get the entire Justin Bieber Believe album.
Go get your free music!
Thanks to Annette for giving me the heads up!
